Key Aspects of the Processes of Thermal Decomposition of Complex Compounds of Copper Formate for Low-Temperature Printed Electronics

Abstract: This work is aimed at studying the fundamentals ensuring the formation of high-quality functional printed copper layers at low temperatures. The paper describes the decomposition of copper formate and its ligand-based complexes: ammonia, ethylamine, diethylamine, and pyridine. Structural and thermal features of the samples were studied by differential thermal analysis, thermogravimetric analysis, and X-ray diffraction analysis. Based on the results of experimental data and quantum-chemical calculations as well… Show more

“…This study represents a logical continuation of the previously published article with the same title, 29 aimed at providing justification and confirmation of the previously proposed hypotheses. Thus, this article presents the results of the study of energetics of the copper formate complex decomposition, both in the solid state and in the DMSO solution.…”

“…This is consistent with the previously proposed assumption about the influence of ligand basicity on the occurrence of side chemical reactions of copper oxides during the decomposition of copper formate complexes. 29 Therefore, since dimethyl sulfoxide is not a base, it is likely that the reaction proceeds via the dehydrogenation pathway to pure copper metal, as evidenced by the quantum chemical calculation of the thermodynamic potentials (ΔE) of competing reactions (Table 1).…”
